3. Product Introduction
3.1 Basic Features
3.1.1 Function
The Sunways STT 80~125kW series is a three-phase grid-connected PV inverter which is used
to e󽗋ciently convert the DC power generated by the PV string into AC power and feed it into
the grid.
3.1.2 The STT 80~125kW series inverter contains 5 models which are list below:
· STT-80KTL, STT-100KTL, STT-110KTL
· STT-100KTL-HV, STT-125KTL-HV
3.1.3 Applicable grid type
The applicable grid types for the Sunways STT 80~125kW series are TN-S, TN-C, TN-C-S, IT and
TT. When applied to the TT grid, the voltage of N to PE should be less than 30V.
· STT-80KTL, STT-100KTL, STT-110KTL, connection mode see Figure 3-1 for details.
· STT-100KTL-HV, STT-125KTL-HV, connection mode see Figure 3-2 for details.
3.1.4 Storage conditions
1) Inverter must be stored in its original packaging.
2) The storage temperature should be in the range of -30 ° C and + 60 ° C , and the relative
humidity stored should be less than 90%.
3) If a batch of inverters needs to be stored, the height of each pile should be no more than 2
levels.
